Illuminated at night (7)
I believe the answer is:
moonlit
'illuminated at night' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for moonlit that I've seen before include "like Titania's unlucky meeting" , "Illuminated by night" , "gently enlightened?" , "Tom lion (anag)" , "like the bank Jessica used?" .)
